Application filed August 19, 1912. Serial No. 715,920.

To /zZZ 107mm z' may concern Be it known that we, GLENN R. SHAFFER and ANDREW M. Sirarrnn, citizens of the United States, residing at Big Bun, in the county of Jefferson, State of Pennsylvania, have invented certain new and useful 1mprovements in Steam-Boiler Fillers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to steam boiler lillers.

The object of the invention resides in the provision of a device of the character named which will automatically regulate the supply of steam to the pump which supplies the boiler with water.

A further object of the invention resides in the provision of a device oi' this character which will be simple in construction, e'llicient in use and which may be installed at a comparatively small cost.

W ith the above and other objects in view the invention consists in the details of construction and in the arrangement and combination ot parts to be hereinafter more fully described and articularly pointed out in the appended claim. l

In describing` the invention in detail reference will be had to the accompanying drawings wherein like characters of referencev denote corresponding parts in the several views, and in which- Figure l is a transverse section through a boiler showing the invention applied and the parts in the position they would occupy when the water in the boiler is above a predetermined level and the supply of steam from the boiler to the pump cut otf. n Fig. 2'

a View similar to F ig. 1 with the parts in thevposition they would occupy when the water in the boiler is below a predetermined level and steam from the boiler is being fed to the pump. Fig. 3 a section on the line 3-8 of Fig. 1. Fig. 4 a. detail perspective View of the float valve employed in the device.

Referring to the drawings, 10 indicates a boiler of any preferred construction. Hung from the upper side oitI the boiler l0 and disposed in the steam space of the Vlatter are hanger lbeams 11. Suspended from the beams 11 is a tubular member 12 provided at its ends with reduced upper and lower extensions 13 and 14 respectively which form shoulders 12. The outerv ends of these extensions are open so as to alord communication between the interior of the boiler and the interior of the member 12 at each end of the latter. Communicating with the interior of the member 12 adjacent its upper end is a steam pipe 15 which extends exteriorly of the boiler and is adapted to supply steam to the pump not shown. Slidably mountedin the major portion of the member 12 and adapted to open and close communicationbetween the pipe 15 and the interior of the member 12 is a float valve B. The valve is formed of a hollow cylindrical member having a bearing llange 16 at each end so as to reduce to a minimum the friction between the valve B andthe member 12 during theimovelnentof the former in the latter.

`W hen the level of the water is as shown in Fig. l or higher the valve B will be buoved up and maintained in the position shown in Fig. l so that no steam from the boiler will pass through the pipe l5 to the pump which supplies water to the boiler. As soon as the level of the waterv in the boiler falls below what is shown vin Fig. 1 the valve B will fall by gravity to the position shown in Fig. 2 when `steam will pass :trom'the boiler through the pipe 15 to the pump and'ei'fect the operation of theflatter until the water is again'raised tothe level shown in Fig. 1. As soon as the level of the water is thus raised the valve B will be buoyed up bythe rise of water to the position shown in Fig. 1 and the supply of steam to the kpump cut off.

Vhat we claim is r The combination of a boiler, a bracket element depending from ythe. top of the boiler within the latter, a tubular vmember supported by said bracket element and having its upper and lower ends reduced torform shoulders, the lower end of said tubular member extending below the normallevel of the water in the boiler, a pipe havingl one end communicating with the interior of the tubular member adjacent the upper shoulder In testimony whereof7 we aflx our signaand its other end dlsposed exterlorly of the tures 1n presence of two witnesses.

boiler, and a hollow cylindrical float Valve s T 1 movable lwithin the tubular member and MS y held against the upper shoulder when the water in the boiler is at its normal level Vtnesses:

whereby communication between the tubular GEORGE S. WEavEm member and pipe is closed. CHARLOTTE iVm-WER.
